One Of The Oil-Free Smooth Bearings -- Composite Bimetallic Bearing

Bimetallic bearing is one of the oil-free smooth bearings

The composite bearing of this product is made of high-quality low-carbon steel back as the matrix, sintered lead-tin bronze alloy on the surface, and rolled into bimetallic strip integrating copper and steel after several high-temperature sintering and fine rolling. It has the characteristics of high bearing capacity, impact resistance, high-temperature resistance and strong self-smoothing ability. It is especially suitable for occasions where it is difficult to smooth and form oil films, such as heavy load, low speed, reciprocating or swing, and is not afraid of water impact and other acid etching and scouring.

 

Because the base plate is stable as low-carbon steel data, the processing accuracy of the outer diameter of the bearing is guaranteed, and the dry bearing does not need to be fixed with screws after the product is installed into the seat hole. The phenomenon of walking the outer circle can be avoided by relying on interference cooperation. The change of the chemical composition of the inner surface alloy layer can meet the requirements of different bearing pressure, different application temperatures and different sliding speeds. The design of oil grooves and oil pockets with different structures on the conflict surface in production can meet the requirements of different refuelling methods and avoid shaft biting.

One Of The Oil-Free Smooth Bearings -- Composite Bimetallic Bearing
The advantages of bimetallic bearings:

The bimetallic bearing has the advantages of good wear resistance, especially suitable for medium speed, medium load, low speed and high load. Through special techniques, various oil grooves, oil holes and oil holes can be processed on the conflict surface, and then adapt to the application under different smooth conditions. The products are mainly used in the balance axle bushing and gasket of heavy vehicles; Automobile engine, chassis, motorcycle clutch, gear pump friction plate and lifting equipment.
